PCI VELOCITY / OPTO ISO RS422/485
After copying the file, Windows 95 will then detect each of the
serial ports in turn and install them as communications ports.
When the "Device Manager" is viewed the PCI R422/485
card will appear under the "Multi-function adapters" branch as
either PCI Velocity RS422/485 card or PCI Opto Iso RS422/485
(parent device). Also, two Velocity RS485 Ports will appear under
the "Ports (COM & LPT) branch" (child device).
For most users who have 4 or less COM ports the new
ports will appear as COM5 and COM6, as pictured below; for
users with more than 5 COM ports the new ports will appear as the
first available COM ports.
